Module: TIMETRA-PORT-MIB

OID (symbolic): TIMETRA-PORT-MIB::tmnxDDMExtCalTxLaserBiasSlope

OID (numeric): 1.3.6.1.4.1.6527.3.1.2.2.4.31.1.46

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-only

Description: The value of tmnxDDMExtCalTxLaserBiasSlope indicates the Tx_l(Slope) value as specified in Table 3.16 in the SFF Committee Standard's document SFF-8472 Rev 10.2.

What is tmnxDDMExtCalTxLaserBiasSlope?

This OID holds a calibration value for an optical transceiver's laser, specifically the slope of how laser output power changes as the bias current increases. This calibration value is essential for the optical module to accurately report its power levels. A technician would use this value when diagnosing why a pluggable optical module is reporting incorrect power readings or when replacing a module with a new one.
